Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.S-tier for open-source model APIs. The default in this space.S-tier in the agent category. The first one I'd give to a non-technical friend.
